The safety and feasibility of laparoscopic common bile duct exploration for treatment patients with previous abdominal surgery

The purpose of this study was to evaluate the safety and feasibility of laparoscopic common bile duct exploration (LCBDE) in patients with previous abdominal surgery (PAS). The outcomes were compared in 139 patients (103 upper and 36 lower abdominal surgeries) with PAS and 361 without PAS who underwent LCBDE. The operative time, hospital stay, rate of open conversion, postoperative complications, duct clearance, and blood loss were compared. Patients with PAS had longer operative times (P = 0.006), higher hospital costs (P = 0.043), and a higher incidence of wound complications (P = 0.011) than those without PAS. However, there were no statistically significant in the open conversion rate, blood loss, hospital stay, bile leakage, biliary strictures, residual stones, and mortality between patients with and without PAS (P > 0.05). Moreover, compared with those without PAS, patients with previous upper abdominal surgery (PUAS) had longer operative times (P = 0.005), higher hospital costs (P = 0.030), and a higher open conversion rate (P = 0.043), but patients with previous lower abdominal surgery (PLAS) had a higher incidence of wound complications (P  = 0.022). LCBDE is considered safe and feasible for patients with PAS, including those with PUAS.
